IMPROVEMENT IN CHAIN WATER-WHEELS.

The Schedule referred `to inthese Letters Patent and mel-:ing part of the same.

To all whom it may concer-nf.-

Be it vknown that I, WILLIAM M. STARR, of the city and county of Washington, in the District of Columbia, have invented a new and useful Improvement in Chain XVater- Wheels, and that the following is a full and exact description thereof, reference being had to the accompanying drawings and to thev letters of reference marked thereon.

My improvement relates to that class ot' waterwheels which employs a chain of buckets.

My invention consists cfa chain oi' buckets, in conibination with, suspended upon, and guided by a single convex drum, thetread'of said chain being curvedv traisversely to fit the drum, which. tapers toward both enc s.

In the accompanying drawings.-

Figure 1 is an end view of my improved waterwheel.

Figure 2 is a front view of the same.

Figures 3, 4, and are detached views.

Figure 6 is a view of the water-inlet or chute.

My improved water-wheel may have any suitable frame, A, forI supporting the drum H and chain of bucketsB.

The drum H maybe made with three or more disks arranged similar to barrel-heads, and then covered' in a suitable manner, forming a drum, tapering toward both endslike a barrel.

The chain of buckets B must be made with a tread having a curve in the directionof their length tofit the drum H, which is of greater diameter in the mid die than toward the ends. v

The links D of the chainproper' are set in pairs, while the links E lit between them, as seen in Iig. 2.

These links are fastened together by rods Nos. l and 2, which have square heads to x them in the links .D, while metallic bushes O, lig. 4, are inserted in the holes of links E, in order 4to bring the slight wear oi' the rods upon these iron bushes or linings of the holcs.

llhese links are also curved longitudinally to fit the circumference of the drum, and the tread of Vthe chain as a whole is curved or made concave transversely, so asto t the drulns taper toward both ends.

After many years experiment I have found that the above simple water-wheel works eiiiciently, the chain always keeping its place without any cogs or guides, wh ich have hitherto been regarded as indispensable to this class of wheels.

In this application I make no claim to a chain of buckets suspended on a straight or cylindrical roller.

Having thus described my invention,

I claiin- The combination ofthe chain of buckets B with thc drum H, tapering toward both ends, all substantially in the manner and for the purposes set forth.
